Dogs
Scientists completed the dog genome sequencing work in 2003. Experts have found that among the more than 24,000 classified genes that have been identified, at least 18,000 are identical to dog genes. Researchers say that from an evolutionary perspective, humans and dogs once had a common ancestor, and the similarity between the human and dog genomes is greater than the similarity between the human and mouse genomes. It is worth mentioning that 30%-50% of a person's character and behavioral characteristics depend on genetic genes.
Scientists believe that the development of dog personality is similar to that of humans. The development of dog personality is related to heredity and the influence of the surrounding living environment, of which heredity is a very important factor. All life movements of animals are controlled by the brain nerves. The basic movement process of the brain nerves is manifested in two methods: stimulation and suppression. How strong are these two methods, whether they are balanced, and how flexible are they to transfer to each other? This determines the dog's different "character".
In addition to genetic factors, a dog’s character will change with changes in the owner’s character, owner’s family members, growth environment, feeding methods and other factors. If a fragile puppy is raised in a home of a person who likes peace, it will gradually get used to an undisturbed environment. As it grows up, it will become more and more fragile. As long as it meets new people, It will show a state of eagerness to run away, or may bark more than once.
They are also weak puppies. If the owner is outgoing and outgoing, he will often take him to noisy crowds, and the puppy will gradually get used to it and gradually change its original weak character. Similarly, if a dog with a good character when he was young meets a taciturn owner and grows up in a quiet environment, he will bark constantly because he is too bored, or he will keep touching him because he is anxious. , which makes the owner feel disgusted, so he will often be criticized. If things go on like this, no matter how good-tempered the puppy is at first, his character will only become worse and worse when he grows up. In other words, part of the reason for the character a dog develops is determined by its owner.
